Careers

People who care about the details tend to do well here.

We are looking for engineers who like understanding how things actually work and are comfortable working close to the core of the system.

If you are fluent in languages like C, C++, Zig, or Rust, and you pay attention to memory, algorithm design, and the shape of the code itself, we should talk.

Bring us work you are proud of, even if it is unfinished. Clear thinking matters more here than polished phrasing.

What we value

A place for people who want technical seriousness without the theater.

Systems thinking

We look for people who can reason about tradeoffs, execution paths, and long-term maintainability.

Craft under pressure

Good work here means remaining precise when the requirements are messy and the constraints are real.

Low-friction collaboration

We keep the team compact and the communication direct so ideas move quickly from discussion to implementation.

Measured outcomes

We care about performance, clarity, and trustworthiness because those are the traits people remember.

Internships
